To (all whom, it may concern.-

Be it known that I, JOHN CHARLES HAY- WARD, a citizen of the UnitedStates. residing will be fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of alubricating mechanism applied to a cylinder, a portion of the cylinderonly being shown. Fig. 2 is a top plan view of the same. Fig. 3 is anenlarged detail View, partially in elevation and partially in section,showing the means for securing a rotary movement in thelubricator-applying means. Fig. 4: is a top plan view of the mechanismfor engaging the spirally-grooved rod or shaft for turning thelubricating means, a portion of the same being shown in section. Fig. 5is a transverse sectional view through the spirally-grooved rod. Fig. 6is a side elevation of the lower end of said rod, the clamp for securingthe lubricator to the said rod being shown in section. Fig. 7 is adetail view of a yoke or cross-head for holding the sweeps or arms whichcarry the lubricating-holders to the spirally-grooved rod.

The device forming the subject-matter of the present invention isdesigned to lubricate the inner surface of cylinder-Walls and is movablymounted with respect to said walls, so that it may be moved out of theway of a piston operating in the cylinder. The device is also given arotary movement, so as to engage a large portion of the cylinder-walls,if not the entire inner surface thereof. I have illustrated in theaccompanying drawings a preferable construction of such a lubricatingmeans, showing the same resting upon the upper end of a piston andcapable of entering the cylinder, following the piston therein, and alsoso mounted as to be lifted from the cylinder by the return movement ofthe piston. The type of cylinder shown is that commonly employed in acompress mechanism and is a cylinder with one end open.

In the said drawings, 1 indicates a cylinder, and 2 a piston-head movingtherein. The piston-rod 3 is secured to the piston-head by means of alarge nut 4, which engages the piston-head, as shown in Fig. 1. Mountedupon the nut/l is a foot-bearing or step 5, which supports the lowertapered end 6 of the rotating shaft 7. The shaft has clamped to it nearits lower end a cross-head or sweepsupporting yoke 8. The cross-head oryoke 8 is formed with a central hub or sleeve 9, which its upon theshaft7, and one or more set-screws, as 10, passing through the wall ofsaid hub, secure the yoke rigidly to the said shaft, so as to be turnedtherewith. The yoke is formed at its opposite ends with recesses,forming seats for the upper ends of sweeps 11. The lower ends of thesweeps extend downwardly to points near the piston 2. Secured to thelower ends of the sweeps are receptacles 12 for containing the lubricantwhich is to be applied to the cylinder. The receptacles 12 are formedwith screw-capped openings 13, by which they may be filled, andextending from the lower end of each receptacle is a delivery-spout 14.Each spout is provided with a valve or stop-cock 15, by which the flowof oil through the spout may be controlled.

To the lower ends of the sweeps are secured lubricating applyingdevices, preferably brushes 16, which extend beneath the outlet ends ofthe spouts 14: and project sufliciently beyond the same to engage thewalls of the cylinder 1. The lubricant is permitted to drip continuallyupon the brushes 16, so as to feed sufiicient of the oil thereto forproperly oiling the inner surface of the cylinder. As the pistonreciprocates in the cylinder the lubricant will be evenly distributedover the inner surface of the cylinder by the brushes 16. In order tomore perfectly apply the lubricant and more evenly spread the same uponthe inner surface of the cylinder, I rotate the shaft 7, which carriesthe lubricating means. In

the drawings I have illustrated a preferred manner of securing therotation of the said shaft 7. The shaft 7 is formed with spiral grooves17, extending longitudinally thereof and upon opposite sides of theshaft with respect to each other. The grooves 17 are made comparativelydeep, as shown in Fig. 5, so that the means which engages them forrotating the shaft may'have a positive hold upon the said shaft. Thedevice employed for engaging the grooves 17 and rotating the shaft ismounted upon a cross-bar 18, which is secured at its ends to the upperends of uprights or standards 19. The said cross-bar 18 is preferablyformed of channel-iron with the flanges turned downwardly. The standards19, which support the channel-bars, are usually formed of angle-iron,and the lower ends may be turned to one side to form an attaching-base20. The attaching-bases of each standard 19 are bolted or otherwisesecured to the upper ends of thecylinder 1. In this manner the cross-bar18 is rigidly supported upon the cylinder and forms a guide for theshaft 7, as well as a support for the means employed in rotating theshaft.

The means for turning the shaft, as shown in the drawings, consists of acasing 21, which is formed with a securing-flange 22, by which it may bebolted or otherwise secured to the bar 18. The central portion of thecasing 1 is made with a bearing 23, which fits upon the shaft 7, andprojecting radially therefrom are guide bearings or boxes 24:, withinwhich are mounted shaft engaging and actuating plugs or bolts 25. Thebolts 25 are tapered at their inner ends 26, so as to fit closely in thegroove 17, formed upon the shaft 7. The outer ends .of the casing areclosed by covers orheads 27, which carry adjusting feed-screws 28. Thefeed-screws 28 hear at their inner ends upon the ends of the bolts orplugs 25 and serve to hold them in engagement with the shaft 7. Theengagement of the said bolts or plugs with the said shaft is a movableone, the screws 28 not being adjusted to such an extent as to preventthe said bolts from slipping easily within the groove 17. The casing 21also carries set-screws 29, which bear upon the sides of the bolts 25and hold them rigidly in their adjusted positions. These set-screws alsocarry jam-nuts 30 for preventing the turning of the set-screws. Theadjusting-screws 28 may also be provided with binding-nuts, as 31, inorder to prevent their turning when not being adjusted.

The shaft 7 rests upon the bearing in the stop or foot-support 5, and asthe piston 2 rises the shaft will be forced to turn by reason of itsengagement with the ends of the bolts 25, so that the brushes 6 will becarried around, spreading oil upon the inner surface of the cylinder.The brushes will thus not only have a reciprocating movement in thecylinder, but will be given a spiral movement, so as to reach all partsof the cylinder. When the piston 2 descends in the cylinder again, the

shaft 7, resting upon the same, will descend, carrying with it itslubricating means and being rotated by the action of its spiral groovesupon the stationary bolts or plugs 25. Vhile the mechanism abovedescribed is especially well adapted for compresses and similarmechanism, it will be apparent that it may be applied to the cylindersof other machines, and if the end of the shaft 7 is connected by aswiveled connection with the piston the mechanism might be arrangedhorizontally or in an inverted manner without departing from the spiritof the invention.

The receptacles 12 may be made large enough to hold a quantity of oilsufficient to lubricate the cylinder for a considerable length of time.The discharge of the oil can be perfectly controlled by setting thevalves 15. Of course the receptacles 12 may be filled from time to timeas required by removing the cap 13.

The plugs 25 may be made of softer metal than the shaft 7, if desired,so that the principal wear in the operation of the oiling device will beupon the said plugs, which can be fed forward from time to time to takeup any lost motion. The plugs of course can also be renewed when theybecome. too short to be serviceable by removing the caps 27 andinserting new ones.
